Introduction
As Large Language Models (LLMs) become increasingly capable, building intelligent systems that can reason, interact, and maintain context across multiple steps is more important than ever. But orchestrating these multi-step workflows is no trivial task with LangGraph.
This article introduces LangGraph, an open-source library built on LangChain that simplifies the creation of stateful and multi-node workflows using Language Models like OpenAI’s GPT. It covers the essentials of setting up LangGraph, illustrating how to create basic and conditional workflows, and discussing the system’s capabilities for maintaining shared state and routing logic based on the outputs of LLMs, thus enabling dynamic and intelligent user interactions.
